When running Linux on a mx28evk and issuing a 'reboot'command the following
behaviour is observed:
root@freescale /$ reboot
starting pid 329, tty '': '/etc/rc.d/rcS stop'
root@freescale /$ Stopping inetd:
Terminated
Unmounting filesystems
umount: tmpfs busy - remounted read-only
chown: /home/user/.rhosts: Read-only file system
chown: /home/user: Read-only file system
chown: /home/user: Read-only file system
cat: can't open '/proc/devices': No such file or directory
The system is going down NOW!
Sent SIGTERM to all processes
Sent SIGKILL to all processes
Requesting system reboot
[ 24.240000] Restarting system.
U-Boot 2011.12-06887-g586ab2f-dirty (Jan 24 2012 - 12:58:50)
Freescale i.MX28 family
DRAM: 0
, and then U-boot hangs.
Calling mx28_power_init() prior to mxs_iomux_setup_multiple_pads() fixes the
problem and
make U-boot to re-start succesfully.

This patch fixes the reboot issue, but I am not able to provide a good
explanation for it, so
I am marking it as RFC.
